I need to flush my brakes, have all the tools to do it, used castrol dot 4 last time, had no issues, just wondering if there is something better? What fluid do you use and in what vehicle?
Doesn't the DOT rating also specify what the fluid is mad of? Read somewhere that you can use dot 3 and 4 interchangeably, and you can mix 5.1 and 4, but never mix 5 with anything else, as its made from a different base fluid?DOT ratings tell you at which temperature the fluid will boil.
I generally stick with Castrol DOT 4. If it's good enough for track motorcycles, it's good enough for me.
It stands to reason that the base formula would differ. Varying levels of glycol and whatever else brake fluid is made from determine the boiling point. I'm no expert in what the chemical makeup of the stuff might be. Why would you want to blend the stuff anyway? It's not like you're driving a F1 car. Stick with what the owner's manual says you should use and don't overthink it.Doesn't the DOT rating also specify what the fluid is mad of?

DOT 3,4 and 5.1 are all glycol based, it's not possible to make an objectively "better" braking fluid without changing the base fluid used it's all just marketing fluff, changing the base fluid would require modifying the entire braking system which is why you cannot use DOT 5 with the others because it's silicone based. Glycol is Glycol, just get any reasonably known brand and you're good to go.
once a month seems really excessive, how does it darken that quickly?RBF660 and replace once a month or when it darkens. No point in getting SRF when it's so much more expensive. Haven't boiled it yet, but have definitely gotten brake fade and heated the fluid up more than I'd like... but I need bigger brakes anyway because they're a joke on my car.
Avoid 5.0 as it's silicone based and can/will eat rubber seals + doesn't mix with glycol based fluid.
Just s2000 things lolonce a month seems really excessive, how does it darken that quickly?
Just did a brake job on a classic car and used midas brake fluid. Works great.Midas brand
